5 Conclusions

Multi-role solutions which allows the concurrent operation of one or more WLAN or Bluetooth® roles are becoming more and more commonly used in many products. The multi-channel multi-role is clearly more complex and challenging to implement than the single-channel one, however it has significant advantages over it like higher throughput and lower power consumption.

WL18xx™ is a great implementation of multi-role multi-channel that meets all challenges and provide great system performance. The results suggest that using the cost-effective WL18xx™ multi-role multi-channel solution with a single radio has several advantages over the multi-role single-channel: Improved throughput for the stations connected to the access point and improved power consumption for the entire system (not covered in the results section)
